S Skeets Member in memoriam Apr 20, 2015 #1 Could you please explain what the letters after Mossberg 500 mean?
D Doyle New member Apr 20, 2015 #3 Yep. A=12ga, B=16ga (rare),C=20ga,D=28Ga (doesn't look like any were actually produced), and E=.410.
B Blindstitch New member Apr 20, 2015 #4 Exactly as Doyle said. Obviously the most common are A and C.
